How to scale the font so that it takes up the entire block?

Question

JavaScript

The success of a light startup on Habré You are a super feat for me to dig in the direction of my mood enhancer on Sunday evening (IE users, sorry).

It only works at 1280x1024 and uses a magic code to calculate the font size centered.style.fontSize = (900 - 3 * message.length) + '%';. At the same time, there are still problems if someone uses + "+".

And how would I make the font size fit to fill the div? Maybe you can adaptively increase it and somehow calculate the size of the resulting block?

Upd. I had to figure it out myself. The link works...

"Quick and dirty" solution:

(hung changing the font size on page load, resizing the window and entering text)
It slows down, but you can bring it to mind if you wish.
